The working principle is as follows:

the big-arch shelter in this application constitutes foundation structure by supporting mechanism 1, installs in ground, and printing opacity subassembly 2 covers outside supporting mechanism 1 from top surface and side to construct the big-arch shelter that has relative enclosure space, receive adverse environmental factor's such as weather and air as avoiding inside vegetation to grow influence. The light-transmitting component 2 comprises a light-transmitting plate 202 and a photovoltaic plate 201, the light-transmitting plate 202 is made of the same material as that of the existing greenhouse, and can be made of various materials such as a soft film and a hard film, so that solar light can irradiate the plants in the greenhouse through the light-transmitting plate 202 to provide necessary natural sunlight for the growth of the plants. The use of photovoltaic board 201 has increased energy-concerving and environment-protective advantage for the big-arch shelter, utilizes photovoltaic board 201 to convert solar energy into the electric energy at big-arch shelter top surface full action, and control mechanism utilizes the electric energy. Specifically, in order to further realize the control to the internal environment of the greenhouse to cultivate more ideal plants, the control mechanism mainly adjusts two main factors of temperature and humidity in the greenhouse, and mainly depends on the electric equipment such as a temperature sensor, a humidity sensor, a heating device and a ventilation device, and the photovoltaic panel 201 provides a power supply for the electric equipment in the control mechanism, so that the agricultural production cost is reduced. It should be noted that the electric energy converted by the photovoltaic panel 201 cannot be directly utilized, and therefore, the control mechanism includes a power transmission device for storing the electric energy and converting the electric energy to be utilized. In addition, in the region with longer sunshine duration, when the generated energy of photovoltaic board 201 is far greater than the required electric quantity of control mechanism work, still can be used for outside other consumer with the electricity generation of photovoltaic board 201, and photovoltaic power generation is utilized to the at utmost, further reduces the power consumption cost and realizes the sustainable development that clean energy utilized.

It is worth explaining that the photovoltaic panel 201 and the light-transmitting plate 202 are arranged at intervals on the top surface of the greenhouse, so that the photovoltaic panel 201 can fully absorb solar energy on the top surface, the energy conversion rate of the photovoltaic panel 201 is improved, the influence of the photovoltaic panel 201 on the light transmittance of the greenhouse can be reduced, and the sunlight can irradiate the greenhouse through the light-transmitting plate 202 on the top surface.

Example 2:
